What tracks deaths on this shed

From this crop only. A factor “rises with deaths” when both move together — it is a clue, not a proof.

Quiet-day targets

Typical house on the days with the lowest deaths this crop. Aim here first, then judge the next crop.

Daily deaths vs water, temp and air

Red bars are birds. Coloured lines are each factor scaled to this crop’s own min–max, so you can see what moves with deaths. Tap a name in the legend to hide it.

Cumulative mortality vs water, temp and air

Same scaling. Use this to see whether a hot or stuffy spell sits under a jump in cum mort.

Water usage per day

Litres. A reading is only complete once the next morning's meter is entered.

Water per 1,000 birds

Corrects for a shrinking flock, so crops of different sizes compare fairly.

Deaths per day

Mort and culls combined.

Cumulative mortality rate

Against mean population. Resets at each thin.

Temperature and humidity

Daily max and min.

Air quality

Limits: CO₂ 3,000 ppm, ammonia 20 ppm.

Average weight

Grams, on weigh days.
